To emini swingtraders: Which brokers allow you to trade 24/24? I heard IB shuts down for an hour around midnight. Is there anything I should know before taking overnighters ex: type of orders not accepted, halted trading procedures etc.? I will be able to monitor the markets during the night session . I am trying to define the maximum risk of gap. Anyone remembers where the eminis were halted the morning of 9/11, and how fast they came down? I can't get accurate data for the NDX on 10/19/87(anyone has a daily chart?) I understand the market gapped down big on that day recovered a bit then plunged in the abyss. How much did it gap down? Are those two instances the worst opens in the last century ?
